+12. Software Sales
+A software company sells a package that retails for $99. 
+Quantity discounts are given according to the following table:
+Quantity      Discount
+10_19          10% 
+20_49          20% 
+50_99          30%
+100 or more    40%
+Write a program that asks the user to enter the number of packages purchased.
+The program should then display the amount of the discount (if any) and the 
+total amount of the purchase after the discount.
